With its classic blend of high strength and low weight, Easton's EA50 stem is a smart choice for your favorite ride. It's made of forged aluminum and sports a shot-peened finish for amazing strength. Easton's Top-Lock technology locks the stem and faceplate together, creating a highly rigid interface while minimizing the loads on the bolts, making the EA50 perfectly safe for carbon bars.
Stem length is measured along the side of the stem from the center of the steerer to the center of the handlebar clamp (see diagram). Keep in mind that as a stem provides more rise, its effective length decreases. In the example above, if the +17-degree stem measures 135 mm, it actually extends 108 mm parallel to the ground.
Clamp Diameter: 31.8mm
Steerer Size: 1 1/8-inch
